KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bekanntlich bleibt, wenn man ein goldplattiertes Rohr immer mehr auszieht, schließlich eine kaum merkbare Öffnung zurück, so daß also auf diese Weise gleichsam eine massive Stange entsteht.As is well known, if you pull out a gold-plated pipe more and more, then ultimately a barely noticeable opening back, so that in this way a massive rod is created, as it were.
Der Gegenstand der Erfindung besteht nun darin, daß man aus der goldplattierten Stange einzelne Stücke von bestimmter Länge abschneidet, diese mit seitlichen konischen Bohrungen versieht, worauf dann die so vorbereiteten zylindrischen Stücke in Gesenken oder durch Ziehen die gewünschte elhpsoidale Außenform und zylindrische Bohrungen erhalten. Nunmehr kann der Gehäuseknopf in bekannter Weise auf beiden Seiten ausgebohrt bzw. ausgefräst werden.The object of the invention is now that one from the gold-plated rod cuts off individual pieces of a certain length, these with lateral conical holes provides, whereupon the so prepared cylindrical pieces in dies or obtain the desired elhpsoidal external shape and cylindrical bores by drawing. The housing button can now be drilled or removed on both sides in a known manner. be milled out.
In beiliegender Zeichnung sind die verschiedenen Stadien des Verfahrens dargestellt. Die runde, goldplattierte Scheibe a. der Fig. 1 wird in bekannter Weise durch eine Maschine allmählich zu einer Röhre b geformt (Fig. 1 und 2), wobei das Arbeitsstück in den verschiedenen Phasen die in der Fig. 1 dargestellten punktiert gezeichneten Formen a', a" annimmt. Die Röhre b wird sodann so lange durch Ziehen weiter verarbeitet, bis sie den gewünschten Durchmesser erreicht hat. Die Dicke der goldplattierten Scheibe α muß derart gewählt werden, daß bei der auf den richtigen Durchmesser gebrachten Röhre δ eine kaum sichtbare innere Öffnung e zurückbleibt, so daß die Röhre als eine massive Stange betrachtet werden kann.The various stages of the process are shown in the accompanying drawing. The round, gold-plated disc a. 1 is gradually formed into a tube b in a known manner by a machine (FIGS. 1 and 2), the workpiece assuming in the various phases the forms a ', a "shown in dotted lines in FIG Tube b is then further processed by drawing until it has reached the desired diameter.The thickness of the gold-plated disc α must be selected in such a way that when the tube δ is brought to the correct diameter, a barely visible inner opening e remains, so that the tube can be viewed as a massive rod.
Zwecks Herstellung von Gehäuseknöpfen wird die Stange sodann in Stücke f von bestimmter Länge geschnitten. Jedes Stück f wird an seinen beiden Enden konisch ausgebohrt (g, Fig. 4) und dann so weiter verarbeitet, bis die gewünschte ellipsoidale Außenform erzeugt ist, die Bohrungen aber zylindrische Form angenommen haben (Fig. 5). Dabei werden die Bohrungen g derart verengt, daß die Zapfen des Uhrringes eingepaßt werden können. Durch Bohren und Fräsen wird noch eine Öffnung h (Fig. 5 und 6) hergestellt, welche gestatten soll, den Gehäuseknopf auf beliebige Weise auf dem Halse der Uhr zu befestigen.For the purpose of producing housing buttons, the rod is then cut into pieces f of a certain length. Each piece f is drilled out conically at both ends (g, Fig. 4) and then processed further until the desired ellipsoidal outer shape is produced, but the bores have assumed a cylindrical shape (Fig. 5). The bores g are narrowed in such a way that the pins of the watch ring can be fitted. An opening h (FIGS. 5 and 6) is made by drilling and milling, which is intended to allow the case button to be attached to the neck of the watch in any desired manner.
